   * Changes
   * -------
   * 01-Jul-2003 : Version 1 contributed by Bryan Scott (DG);
   * 27-Apr-2005 : Change XYDataset --> TableXYDataset because the table model
   *               assumes all series share the same x-values, and this is not
   *               enforced by XYDataset.  Also fixed bug 1191046, a problem
   *               in the getValueAt() method (DG);
